1.	Which type of weigher is commonly used all over the world?(a) Electronic weighers(b) Mechanical weighers(c) Pneumatic weighers(d) Nuclear weighersI got this question by my school principal while I was bunking the class.My doubt stems from Coal Weighing Methods in section Steam Power Plant of Energy Engineering
Answer» The correct answer is (B) Mechanical weighers The explanation is: Mechanical weigher is commonly used all over world. This based on mechanical principle. This works on a lever system mounted on knife edges and bearings that connected to a resistant like a SPRING or pendulum. The resultant VALUE obtained by multiplication of load and speed VALUES is displayed by a digital counter.
